Timbren Suspension Kits (SES Kits) are designed to enhance the suspension of your vehicle.

Towing top-heavy loads, like your RV trailer, can impact your ability to keep the trailer moving on a straight path down the highway. This doesn’t just make for a challenging drive — it’s dangerous.

Designed exclusively for RV trailers, Timbren SES kits for trailers keep your load level at all times. This creates a safe, controlled ride so smooth, you might forget you’re towing your RV trailer altogether.

How? Our Aeon® springs deliver a progressive spring rate. As load increases, our springs push back harder, eliminating your RV trailer’s squat, sway, and roll while providing a safe, smooth ride. The natural rubber properties of our Aeon® springs also cushion road shock, reducing hard hits on your trailer from driving over bumps and dips.

This SES suspension upgrade fits your RV trailer suspension with an underslung axle setup that has a 2 ⅜-inch to 3-inch diameter axle with 2-inch wide leaf springs. Each laser cut piece of steel is precision bent and powder-coated to ensure a quality fit.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, our kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.

Key Features:

  • Eliminates trailer squatting and sagging
  • Cushions road shocks
  • Improves handling
  • DIY installation
  • Zero post-installation maintenance

Specs: Rated Capacity: 15,000 lbs

Note: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the trailer’s GTW (Gross Trailer Weight). Please make sure that the load does not exceed the GTW set by the manufacturer.

What's Included:

  • 2 x Mounting discs
  • 2 x Lower mounting assembly
  • 2 x Patented Aeon® SES suspensions (hollow rubber springs)
  • All necessary hardware

Great to clean up the cable clutter
Size: 50mm/2inch, Color: Black, Number of Items: 4
I finally got around to cleaning up the cable disaster on my home office desk and these grommets were exactly what I needed. They fit perfectly into the 2-inch holes I drilled, and the plastic feels surprisingly sturdy, not like that cheap, brittle stuff that snaps the moment you try to pop the cover back on. The little brush-like opening is a nice touch because it keeps the cords from sliding back down when they aren't plugged in, and the black finish looks really clean against my wood tabletop. For a 4-pack, the price was a total steal, and it honestly makes the whole setup look way more professional than just having raw holes in the desk. If humans are looking for a quick and cheap way to hide cord clutter, these are a solid bet.

I used this grommet for the entertainment center wall behind my TV and it looks good and works great. Came with all the tools I needed to cut the hole in the wall and install it.

I bought these to provide a snug fit for an EV charging cable running through my garage wall. They worked perfectly to keep out drafts and crawly things. Highly recommended.
